Elder abuse geriatrics: describing an important new medical specialist

Elder mistreatment, including elder abuse and neglect, is a difficult diagnosis to make and manage for most providers. To address this, two elder abuse consultation teams were developed for patients in the hospital and emergency department settings. As these teams have developed, the providers involved have obtained specialized training and experience that we believe contributes to a new field of elder abuse geriatrics, a corollary to the well-established field of child abuse pediatrics. Providers working in this field require specialized training and have a specialized scope of practice that includes forensic evaluation, evaluation of cognition and capacity, care coordination and advocacy for victims of abuse, and collaboration with protective services and law enforcement. Here we describe the training, scope of practice, ethical role, and best practices for elder mistreatment medical consultation. We hope this will serve as a starting point for this new and important medical specialty.

ED/hospital program contributions to community multi-disciplinary team meetings: Different models

Elder mistreatment (EM) is a complex problem, with response and prevention requiring contributions from professionals from many disciplines. Community-based multi-disciplinary teams (MDTs) that conduct meetings to discuss challenging cases and coordinate services are a common strategy to ensure effective collaboration. Though they play an important role in EM identification, intervention, and prevention, hospitals and hospital-based healthcare professionals have been particularly difficult to engage in MDTs. Two hospitals in different communities recently launched Emergency Department (ED)/hospital-based response teams to consult in cases of potential EM, and both participate in MDTs. We explored similarities and differences between the MDTs in these communities including in the role of the ED/hospital-based response team. The comparison demonstrates both core common features as well as large variations. These differences reflect different circumstances in the models on which they were based, on MDT development in these communities, available resources and infrastructure, and the ED/hospital program's role.

Healthcare costs for legally adjudicated elder mistreatment victims in comparison to non-mistreated older adults

BACKGROUND

Elder mistreatment (EM) is associated with adverse health outcomes and healthcare utilization patterns that differ from other older adults. However, the association of EM with healthcare costs has not been examined. Our goal was to compare healthcare costs between legally adjudicated EM victims and controls.

METHODS

We used Medicare insurance claims to examine healthcare costs of EM victims in the 2 years surrounding initial mistreatment identification in comparison to matched controls. We adjusted costs using the Centers for Medicare and Medicaid Services Hierarchical Condition Categories (CMS-HCC) risk score.

RESULTS

We examined healthcare costs in 114 individuals who experienced EM and 410 matched controls. Total Medicare Parts A and B healthcare costs were similar between cases and controls in the 12 months prior to initial EM detection ($11,673 vs. $11,402, p = 0.92), but cases had significantly higher total healthcare costs during the 12 months after initial mistreatment identification ($15,927 vs. $10,805, p = 0.04). Adjusting for CMS-HCC scores, cases had, in the 12 months after initial EM identification, $5084 of additional total healthcare costs (95% confidence interval [$92, $10,077], p = 0.046) and $5817 of additional acute/subacute/post-acute costs (95% confidence interval [$1271, $10,362], p = 0.012) compared with controls. The significantly higher total costs and acute/sub-acute/post-acute costs among EM victims in the post-year were concentrated in the 120 days after EM detection.

CONCLUSIONS

Older adults experiencing EM had substantially higher total costs during the 12 months after mistreatment identification, driven by an increase in acute/sub-acute/post-acute costs and focused on the period immediately after initial EM detection.

Strategies for dissemination of ED/hospital elder mistreatment response team model

Interdisciplinary Emergency Department/hospital-based teams represent a promising care model to improve identification of and intervention for elder mistreatment. Two institutions, Weill Cornell Medicine/NewYork-Presbyterian Hospital and the University of Colorado Anschutz Medical Campus have launched such programs and are exploring multiple strategies for effective dissemination. These strategies include: (1) program evaluation research, (2) framing as a new model of geriatric care, (3) understanding the existing incentives of health systems, EDs, and hospitals to align with them, (4) connecting to ongoing ED/hospital initiatives, (5) identifying and collaborating with communities with strong elder mistreatment response that want to integrate the ED/hospital, (6) developing and making easily accessible high-quality, comprehensive protocols and training materials, (7) offering technical assistance and support, (8) communications outreach to raise awareness, and (9) using an existing framework to inform implementation in new hospitals and health systems.

Elder Mistreatment: Emergency Department Recognition and Management

Elder mistreatment is experienced by 5% to 15% of community-dwelling older adults each year. An emergency department (ED) encounter offers an important opportunity to identify elder mistreatment and initiate intervention. Strategies to improve detection of elder mistreatment include identifying high-risk patients; recognizing suggestive findings from the history, physical examination, imaging, and laboratory tests; and/or using screening tools. ED management of elder mistreatment includes addressing acute issues, maximizing the patient's safety, and reporting to the authorities when appropriate.

Initial steps in addressing the challenges of elder mistreatment evaluation: Protocol for evaluating the Vulnerable Elder Protection Team

INTRODUCTION

Although many programmes have been developed to address elder mistreatment, high-quality, rigorous evaluations to assess their impact are lacking. This is partly due to challenges in conducting programme evaluation for such a complex phenomenon. We describe here the development of a protocol to mitigate these challenges and rigorously evaluate a first-of-its-kind emergency department/hospital-based elder mistreatment intervention, the Vulnerable Elder Protection Team (VEPT).

METHODS AND ANALYSIS

We used a multistep process to develop an evaluation protocol for VEPT: (1) creation of a logic model to describe programme activities and relevant short-term and long-term outcomes, (2) operationalisation of these outcome measures, (3) development of a combined outcome and (4) design of a protocol using telephone follow-up at multiple time points to obtain information about older adults served by VEPT. This protocol, which is informing an ongoing evaluation of VEPT, may help researchers and health system leaders design evaluations for similar elder mistreatment programmes.

ETHICS AND DISSEMINATION

This project has been reviewed and approved by the Weill Cornell Medicine Institutional Review Board, protocol #20-02021422. We aim to disseminate our results in peer-reviewed journals at national and international conferences and among interested patient groups and the public.

The critical role of the specialized social worker as part of ED/hospital-based elder mistreatment response teams

The emergency department and hospital provide a unique and important opportunity to identify elder mistreatment and offer intervention. To help manage these complex cases, multi-disciplinary response teams have been launched. In developing these teams, it quickly became clear that social workers play a critical role in responding to elder mistreatment. Their unique skillset allows them to establish close connections with community resources, collaborate with various hospital stakeholders, support patients/families/caregivers through challenging situations, navigate the legal and protective systems, and balance patient safety and quality of life in disposition decision-making. The role of the social worker on these multi-faceted teams includes conducting a comprehensive biopsychosocial assessment, helping to develop a safe discharge plan, and making appropriate referrals, among other responsibilities. Any institution considering developing a multi-disciplinary program should recognize the critical importance of social work.

Mechanisms and weapons in physical elder abuse injuries: Findings from legally adjudicated cases

INTRODUCTION

Elder abuse is common, but many characteristics have not been well-described, including injury mechanisms and weapons in physical abuse. Better understanding of these may improve identification of elder abuse among purportedly unintentional injuries. Our goal was to describe mechanisms of injury and weapons used and their relation to injury patterns.

METHODS

We partnered with District Attorney's offices in 3 counties and systematically examined medical, police, and legal records from 164 successfully prosecuted physical abuse cases of victims aged ≥60 from 2001 to 2014.

RESULTS

Victims sustained 680 injuries (mean 4.1, median 2.0, range 1-35). Most common mechanisms were: blunt assault with hand/fist (44.5%), push/shove, fall during altercation (27.4%), and blunt assault with object (15.2%). Perpetrators more commonly used body parts as weapons (72.6%) than objects (23.8%). Most commonly used body parts were: open hands (55.5% of victims sustaining injuries from body parts), closed fists (53.8%), and feet (16.0%). Most commonly used objects were: knives (35.9% of victims sustaining injuries from objects) and telephones (10.3%). The most frequent mechanism/injury location pair was maxillofacial/dental/neck injury by blunt assault with hand/fist (20.0% of all injuries). The most frequent mechanism/injury type pair was bruising by blunt assault with hand/fist (15.1% of all injuries). Blunt assault with hand/fist injury was positively associated with victim female sex (OR: 2.27, CI: [1.08 - 4.95]; p = 0.031), while blunt assault with object mechanisms was inversely associated with victim female sex (OR: 0.32, CI: [0.12 - 0.81]; p = 0.017).

CONCLUSION

Physical elder abuse victims are more commonly assaulted with an abuser's body part than an object, and the mechanisms and weapons used impact patterns of injury.

Adult Protective Services Perspectives on Responding to Elder Abuse and Serving Clients During the COVID-19 Pandemic

The initial COVID-19 pandemic and subsequent public health measures dramatically impacted Adult Protective Services (APS), requiring rapid adjustments. Our goal was to describe challenges for APS and strategies developed to respond. We conducted six focus groups and seven interviews during March-April 2021 using a semi-structured topic guide, with 31 participants from APS leadership, supervisors, and caseworkers in New York City, a community hard hit by the initial COVID surge. Data from transcripts were analyzed to identify themes. Participants identified challenges faced by APS (e.g., clients less willing to engage with APS, inability to perform necessary job tasks remotely, and low staffing levels) as well as strategies APS used in response (e.g., increasing collaboration with other community-based programs and service providers, enabling remote court hearings through technology and in-person facilitation, and ensuring staff had access to personal protective equipment). These findings may inform APS planning for future large-scale societal disruptions.

Leveraging VA geriatric emergency department accreditation to improve elder abuse detection in older Veterans using a standardized tool

Elder abuse (EA) is common and has devastating health impacts, yet most cases go undetected limiting opportunities to intervene. Older Veterans receiving care in the Veterans Health Administration (VHA) represent a high-risk population for EA. VHA emergency department (ED) visits provide a unique opportunity to identify EA, as assessment for acute injury or illness may be the only time isolated older Veterans leave their home, but most VHA EDs do not have standardized EA assessment protocols. To address this, we assembled an interdisciplinary team of VHA social workers, physicians, nurses, intermediate care technicians (ICTs; former military medics and corpsmen who often conduct screenings in VHA EDs) and both VHA and non-VHA EA subject matter experts to adapt the Elder Mistreatment Screening and Response Tool (EM-SART) to pilot in the Louis Stokes Cleveland VA Medical Center geriatric ED (GED) program. The cornerstone of their approach is an interdisciplinary GED consultation led by ICTs and nurses who screen high-risk older Veterans for geriatric syndromes and unmet needs. The adapted EM-SART was integrated into the electronic health record and GED workflow in December 2020. By July 2022, a total of 251 Veterans were screened with nine (3.6%) positive on the prescreen and five (2%) positive on the comprehensive screen. Based on the first-year pilot experience, the interdisciplinary team was expanded and convened regularly to further adapt the EM-SART for wider use in VHA, including embedding flexibility for both licensed and nonlicensed clinicians to complete the screening tool and tailoring response options to be specific to VHA policy and resources. The national momentum for VHA EDs to improve care for older Veterans and secure GED accreditation offers unique opportunities to embed this evidence-based approach to EA assessment in the largest integrated health system in the United States.

Emergency Department and Hospital Utilization Among Older Adults Before and After Identification of Elder Mistreatment

Importance

Elder mistreatment is common and has serious health consequences. Little is known, however, about patterns of health care utilization among older adults experiencing elder mistreatment.

Objective

To examine emergency department (ED) and hospital utilization of older adults experiencing elder mistreatment in the period surrounding initial mistreatment identification compared with other older adults.

Design, Setting, and Participants

This retrospective case-control study used Medicare insurance claims to examine older adults experiencing elder mistreatment initially identified between January 1, 2003, and December 31, 2012, and control participants matched on age, sex, race and ethnicity, and zip code. Statistical analysis was performed in April 2022.

Main Outcomes and Measures

We used multiple measures of ED and hospital utilization patterns (eg, new and return visits, frequency, urgency, and hospitalizations) in the 12 months before and after mistreatment identification. Data were adjusted using US Centers for Medicare and Medicaid Services Hierarchical Condition Categories risk scores. Chi-squared tests and conditional logistic regression models were used for data analyses.

Results

This study included 114 case patients and 410 control participants. Their median age was 72 years (IQR, 68-78 years), and 340 (64.9%) were women. Race and ethnicity were reported as racial or ethnic minority (114 [21.8%]), White (408 [77.9%]), or unknown (2 [0.4%]). During the 24 months surrounding identification of elder mistreatment, older adults experiencing mistreatment were more likely to have had an ED visit (77 [67.5%] vs 179 [43.7%]; adjusted odds ratio [AOR], 2.95 [95% CI, 1.78-4.91]; P < .001) and a hospitalization (44 [38.6%] vs 108 [26.3%]; AOR, 1.90 [95% CI, 1.13-3.21]; P = .02) compared with other older adults. In addition, multiple ED visits, at least 1 ED visit for injury, visits to multiple EDs, high-frequency ED use, return ED visits within 7 days, ED visits for low-urgency issues, multiple hospitalizations, at least 1 hospitalization for injury, hospitalization at multiple hospitals, and hospitalization for ambulatory care sensitive conditions were substantially more likely for individuals experiencing elder mistreatment. The rate of ED and hospital utilization for older adults experiencing elder mistreatment was much higher in the 12 months after identification than before, leading to more pronounced differences between case patients and control participants in postidentification utilization. During the 12 months after identification of elder mistreatment, older adults experiencing mistreatment were particularly more likely to have had high-frequency ED use (12 [10.5%] vs 8 [2.0%]; AOR, 8.23 [95% CI, 2.56-26.49]; P < .001) and to have visited the ED for low-urgency issues (12 [10.5%] vs 8 [2.0%]; AOR, 7.33 [95% CI, 2.54-21.18]; P < .001).

Conclusions and Relevance

In this case-control study of health care utilization, older adults experiencing mistreatment used EDs and hospitals more frequently and with different patterns during the period surrounding mistreatment identification than other older adults. Additional research is needed to better characterize these patterns, which may be helpful in informing early identification, intervention, and prevention of elder mistreatment.

APS PERSPECTIVES ON CHALLENGES AND STRATEGIES SERVING CLIENTS DURING THE COVID-19 PANDEMIC SURGE

The initial surge of the COVID-19 pandemic and public health measures in response dramatically impacted Adult Protective Services’ (APS) ability to conduct investigations and provide services, requiring agencies to quickly adapt. Our goal was to describe challenges for APS and strategies they developed to respond. We conducted 6 focus groups and 7 interviews during March-April 2021 used a semi-structured topic guide, with 31 participants from APS leadership, supervisors, and case workers in New York City, a community hard hit by the initial COVID surge. Focus groups and interviews were recorded and transcribed, with data analyzed to identify themes. Participants identified 9 major challenges, including: clients using concern about COVID-19 to refuse APS workers’ access to their home, necessity to perform home visits/wellness checks on behalf of other agencies who had suspended home visits, and dependence on in-office activities including receiving paper mail. Participants reported 30 formal and informal strategies adopted to address challenges. These included 13 focusing on maximizing client engagement while maintaining client and APS worker safety, such as: adding a pre-investigation before a home visit to assess COVID-19 risk/exposure, offering clients masks and hand sanitizer to build trust, and close collaboration with other agencies/programs including joint visits. Also, 17 strategies were reported to allow for remote work and support staff, including: modifying processes to replace paper mail with electronic communication/processing, offering counseling services, formally recognizing excellent performance, and leadership reaching out personally to check on staff members. These findings may inform APS planning for future large-scale societal disruptions.

Vulnerable Elder Protection Team: Initial experience of an emergency department-based interdisciplinary elder abuse program

BACKGROUND

An emergency department (ED) visit provides a unique opportunity to identify elder abuse and initiate intervention, but emergency providers rarely do. To address this, we developed the Vulnerable Elder Protection Team (VEPT), an ED-based interdisciplinary consultation service. We describe our initial experience in the first two years after the program launch.

METHODS

We launched VEPT in a large, urban, academic ED/hospital. From 4/3/17 to 4/2/19, we tracked VEPT activations, including patient characteristics, assessment, and interventions. We compared VEPT activations to frequency of elder abuse identification in the ED before VEPT launch. We examined outcomes for patients evaluated by VEPT, including change in living situation at discharge. We assessed ED providers' experiences with VEPT via written surveys and focus groups.

RESULTS

During the program's initial two years, VEPT was activated and provided consultation/care to 200 ED patients. Cases included physical abuse (59%), neglect (56%), financial exploitation (32%), verbal/emotional/psychological abuse (25%), and sexual abuse (2%). Sixty-two percent of patients assessed were determined by VEPT to have high or moderate suspicion for elder abuse. Seventy-five percent of these patients had a change in living/housing situation or were discharged with new or additional home services, with 14% discharged to an elder abuse shelter, 39% to a different living/housing situation, and 22% with new or additional home services. ED providers reported that VEPT made them more likely to consider/assess for elder abuse and recognized the value of the expertise and guidance VEPT provided. Ninety-four percent reported believing that there is merit in establishing a VEPT Program in other EDs.

CONCLUSION

VEPT was frequently activated and many patients were discharged with changes in living situation and/or additional home services, which may improve safety. Future research is needed to examine longer-term outcomes.

Geriatric Burn Injuries Presenting to the Emergency Department of a Major Burn Center: Clinical Characteristics and Outcomes

BACKGROUND

Burn injuries in geriatric patients are common and may have significant associated morbidity and mortality. Most research has focused on the care of hospitalized patients after admission to burn units. Little is known about the clinical characteristics of geriatric burn victims who present to the emergency department (ED) and their ED assessment and management.

OBJECTIVE

Our aim was to describe the clinical characteristics and outcomes of geriatric patients presenting to the ED with burn injuries.

METHODS

We performed a comprehensive retrospective chart review on all patients 60 years and older with a burn injury presenting from January 2011 through September 2015 to a large, urban, academic ED in a hospital with a 20-bed burn center.

RESULTS

A total of 459 patients 60 years and older were treated for burn injuries during the study period. Median age of burn patients was 71 years, 23.7% were 80 years and older, and 56.6% were female. The most common burn types were hot water scalds (43.6%) and flame burns (23.1%). Median burn size was 3% total body surface area (TBSA), 17.1% had burns > 10% TBSA, and 7.8% of patients had inhalation injuries. After initial evaluation, 46.4% of patients were discharged from the ED. Among patients discharged from the ED, only 1.9% were re-admitted for any reason within 30 days. Of the patients intubated in the ED, 7.1% were extubated during the first 2 days of admission, and 64.3% contracted ventilator-associated pneumonia.

CONCLUSIONS

Better understanding of ED care for geriatric burn injuries may identify areas in which to improve emergency care for these vulnerable patients.

Emergency Department Utilization Patterns Among Physical Elder Abuse Victims in Comparison to Other Older Adults

Background: Physical elder abuse is common and has serious health consequences. Little is known, however, about the patterns of health care utilization among these victims, including whether opportunities may exist for earlier identification and intervention. Our goal was to describe Emergency Department (ED) utilization known physical elder abuse victims compared with non-victims. Methods: We used Medicare insurance claims to examine ED utilization patterns among a well-characterized cohort of 139 known physical elder abuse victims in the year before abuse was identified and compared this to control subjects matched on age, sex, race, and residential zip code. Results: Physical elder abuse victims were significantly more likely than control subjects to visit the ED (47.5% vs. 35.9%, p=0.01) during the year before identification and to have at least one visit for an injury-related complaint (14.4% vs. 8.3%, p=0.03). Victims were also more likely to have multiple visits (18.7% vs. 14.6%, p=0.24), visit multiple EDs (7.9% vs. 6.7%, p=0.63), or be high frequency utilizers (≥4 visits, 3.6% vs. 2.7%, p=0.58), but differences did not reach statistical significance. The most common diagnoses in ED visits among victims were: open wound of knee/ankle, exacerbation of chronic bronchitis, pneumonia, and chest pain. Conclusion: This work provides preliminary evidence that physical elder abuse victims use the ED more frequently and potentially have different patterns of utilization than other older adults. We plan to further characterize these different patterns to potentially to use them to develop tools for earlier identification.

Development of the Verbal Autopsy Instrument for COVID-19 (VAIC)

BACKGROUND

Improving accuracy of identification of COVID-19-related deaths is essential to public health surveillance and research. The verbal autopsy, an established strategy involving an interview with a decedent's caregiver or witness using a semi-structured questionnaire, may improve accurate counting of COVID-19-related deaths.

OBJECTIVE

To develop and pilot-test the Verbal Autopsy Instrument for COVID-19 (VAIC) and a death adjudication protocol using it.

METHODS/KEY RESULTS

We used a multi-step process to design the VAIC and a protocol for its use. We developed a preliminary version of a verbal autopsy instrument specifically for COVID. We then pilot-tested this instrument by interviewing respondents about the deaths of 15 adults aged ≥65 during the initial COVID-19 surge in New York City. We modified it after the first 5 interviews. We then reviewed the VAIC and clinical information for the 15 deaths and developed a death adjudication process/algorithm to determine whether the underlying cause of death was definitely (40% of these pilot cases), probably (33%), possibly (13%), or unlikely/definitely not (13%) COVID-19-related. We noted differences between the adjudicated cause of death and a death certificate.

CONCLUSIONS

The VAIC and a death adjudication protocol using it may improve accuracy in identifying COVID-19-related deaths.

Developing a tool to assess and monitor institutional readiness to address elder mistreatment in hospital emergency departments

Hospital emergency departments (EDs) lack the tools and processes required to facilitate consistent screening and intervention in cases of elder abuse and neglect. To address this need, the National Collaboratory to Address Elder Mistreatment has developed a clinical care model that ED's can implement to improve screening, referral, and linkage to coordinated care and support services for older adults who are at risk of mistreatment. To gauge ED readiness to change and facilitate adoption of the care model, we developed an organizational assessment tool, the Elder Mistreatment Emergency Department Assessment Profile (EM-EDAP). Development included a phased approach in which we reviewed evidence on best practice; consulted with multidisciplinary experts; and sought input from ED staff. Based on this formative research, we developed a tool that can be used to guide EDs in focusing on practice improvements for addressing elder mistreatment that are most responsive to local needs and opportunities.

Diagnostic Coding of Elder Mistreatment: Results From a National Database of Medicare Advantage and Private Insurance Patients, 2011-2017

Health care providers may play an important role in detection of elder mistreatment, which is common but underrecognized. We used the Health Care Cost Institute insurance claims database to describe elder mistreatment diagnosis among Medicare Advantage (MA) and private insurance patients in the United States from 2011 to 2017. We used International Classification of Diseases (ICD) coding to identify cases, examining the impact of transition from ICD-9 (Ninth Revision) to ICD-10 (Tenth Revision), which occurred in October 2015 and added 14 new codes for "suspected" mistreatment. 8,127 patients (0.051% of all aged ≥ 65), including 6,304 with MA (0.058%) and 1,823 with private insurance (0.026%) received elder mistreatment diagnosis. Transition from ICD-9 to ICD-10 was associated with a small increase in diagnosis rate, with "suspected" codes used in 45.3% of ICD-10 versus 9.7% of ICD-9 cases. Overall rates remained low. Rates, settings, and types of diagnosis differed between MA and private insurance patients.

Identifying patterns of health care utilisation among physical elder abuse victims using Medicare data and legally adjudicated cases: protocol for case-control study using data linkage and machine learning

INTRODUCTION

Physical elder abuse is common and has serious health consequences but is under-recognised and under-reported. As assessment by healthcare providers may represent the only contact outside family for many older adults, clinicians have a unique opportunity to identify suspected abuse and initiate intervention. Preliminary research suggests elder abuse victims may have different patterns of healthcare utilisation than other older adults, with increased rates of emergency department use, hospitalisation and nursing home placement. Little is known, however, about the patterns of this increased utilisation and associated costs. To help fill this gap, we describe here the protocol for a study exploring patterns of healthcare utilisation and associated costs for known physical elder abuse victims compared with non-victims.

METHODS AND ANALYSIS

We hypothesise that various aspects of healthcare utilisation are differentially affected by physical elder abuse victimisation, increasing ED/hospital utilisation and reducing outpatient/primary care utilisation. We will obtain Medicare claims data for a series of well-characterised, legally adjudicated cases of physical elder abuse to examine victims' healthcare utilisation before and after the date of abuse detection. We will also compare these physical elder abuse victims to a matched comparison group of non-victimised older adults using Medicare claims. We will use machine learning approaches to extend our ability to identify patterns suggestive of potential physical elder abuse exposure. Describing unique patterns and associated costs of healthcare utilisation among elder abuse victims may improve the ability of healthcare providers to identify and, ultimately, intervene and prevent victimisation.

ETHICS AND DISSEMINATION

This project has been reviewed and approved by the Weill Cornell Medicine Institutional Review Board, protocol #1807019417, with initial approval on 1 August 2018. We aim to disseminate our results in peer-reviewed journals at national and international conferences and among interested patient groups and the public.

Substance Use Is Common in Elder Abuse Cases: Qualitative Findings From a Multi-Disciplinary Team

Elder abuse is mistreatment of an older adult by a caregiver or another person in a position with an expectation of trust. Adversely affecting as many as 10% of community-dwelling older adults in the US, it may include physical abuse, sexual abuse, psychological abuse, financial exploitation and neglect. Mental illness and substance use by caregivers, family members and victims themselves have been described as risk factors for multiple forms of elder abuse in prior cross-sectional analyses but the impact on these cases is poorly understood. To explore this association we conducted a focus group using a semi-structured format involving an inter-disciplinary group of elder abuse professionals that are part of the New York City Elder Abuse Center enhanced multi-disciplinary team (EMDT) in Staten Island, New York. Focus group participants reported that opioid, cocaine, cannabis and alcohol use is common among perpetrators of elder abuse, especially in cases of financial mistreatment, verbal and physical abuse. Other potential consequences included eviction of the older adult victim, co-dependency and involvement of the older adult in the procurement of illicit substances, and substance use by the older adult. Respondents specifically expressed concerns that the opioid epidemic, including rising heroin use, may be changing the frequency and nature of elder abuse, and that case investigations offer an opportunity to facilitate referrals for formal substance use disorder assessment and treatment. Future work includes additional focus groups and quantitative analysis to clarify the intersection between substance use and elder abuse and inform intervention and prevention strategies.

Prosecution of Elder Neglect: A Close Examination of Cases From King County, Washington

Elder neglect is common and can have catastrophic consequences. Cases may benefit from integrated responses from multiple sectors. Little research exists describing prosecutorial involvement and its impact, but existing evidence suggests neglect is seldom criminally prosecuted. Our goal was to closely examine neglect prosecution in a jurisdiction that has been a leader in using prosecution to attempt to address it. We quantitatively and qualitatively analyzed legal case files of felony elder neglect prosecuted in King County, Washington from 2008-2011. 13 cases were prosecuted, with a total of 10 victims. 90% of victims were female, with a median age of 88. 90% were unable to ambulate, and 90% had dementia. Defendants were commonly the victim’s adult child (38%). 23% had previous criminal citations/convictions. 46% of cases occurred in an Adult Family Home. 15% of cases went to trial, and all trial cases ended in conviction of some charge. Themes identified included: (1) perpetrators were either professional caregivers receiving compensation or non-professional caregivers financially dependent on the victim, (2) victims were malnourished and severely injured at time of reporting, and (3) medical expert contribution is imperative given complexity of these cases. Victims were unable to participate in prosecution in any case. This research shows that these cases are seldom prosecuted, even in a jurisdiction focusing on this phenomenon, but highlights characteristics of cases and demonstrates they may be prosecuted without victim participation. Future research is needed to examine prosecution’s impact on elder neglect to better understand how it may be optimally used.

Exploring Risk of Elder Abuse Revictimization: Development of a Model to Inform Community Response Interventions

A focus of community-based elder abuse response programs (EARP), such as Adult Protective Services, is to reduce the risk of revictimization among substantiated victims. While elder abuse (EA) risk factor research has predominantly focused on understanding the risk of initial EA onset among the general older adult population, understanding of revictimization risk among substantiated victims is weak. This study sought to identify conditions that perpetuate EA among substantiated victims. Data were collected from multiple sources: focus groups with multidisciplinary teams ( n = 35), multidisciplinary team case revictimization risk evaluations ( n = 10), and reviewing a random sample of case records ( n = 250) from a large EARP in New York City. Sixty-two indicators of EA revictimization risk were identified across several ecosystemic levels: individual victim or perpetrator, victim–perpetrator relationship, and surrounding family, home, community, and sociocultural contexts. Findings carry implications for EARP practices to reduce EA recurrence and the development of measures to evaluate EARP intervention.

Developing standard data for elder abuse multidisciplinary teams: A critical objective

Multidisciplinary teams (MDTs) represent a prominent and growing form of elder abuse intervention in communities across the U.S. and around the world. Despite the proliferation and promise of MDTs as a model of elder abuse intervention, the field lacks infrastructure, including a standardized data collection strategy, to facilitate a coordinated and informed MDT effort. This commentary presents an exploratory study, which sought to examine existing strategies of case-level electronic data collection implemented by MDTs across the U.S. Using a snowball sampling strategy, we identified 11 MDTs using an electronic data collection strategy. Our analysis found a tremendous range in both the extent and nature of data collection across MDTs, yet it identified common domains of data. A standardized MDT data collection strategy would benefit several MDT stakeholders, including coordinators tracking everyday operations, funders requiring reporting, and researchers conducting large-scale comparative research to identify best MDT practices.

Identifying Injury Patterns Associated With Physical Elder Abuse: Analysis of Legally Adjudicated Cases

STUDY OBJECTIVE

Elder abuse is common and has serious health consequences but is underrecognized by health care providers. An important reason for this is difficulty in distinguishing between elder abuse and unintentional trauma. Our goal was to identify injury patterns associated with physical elder abuse in comparison with those of patients presenting to the emergency department (ED) with unintentional falls.

METHODS

We partnered with a large, urban district attorney's office and examined medical, police, and legal records from successfully prosecuted cases of physical abuse of victims aged 60 years or older from 2001 to 2014.

RESULTS

We prospectively enrolled patients who presented to a large, urban, academic ED after an unintentional fall. We matched 78 cases of elder abuse with visible injuries to 78 unintentional falls. Physical abuse victims were significantly more likely than unintentional fallers to have bruising (78% versus 54%) and injuries on the maxillofacial, dental, and neck area (67% versus 28%). Abuse victims were less likely to have fractures (8% versus 22%) or lower extremity injuries (9% versus 41%). Abuse victims were more likely to have maxillofacial, dental, or neck injuries combined with no upper and lower extremity injuries (50% versus 8%). Examining precise injury locations yielded additional differences, with physical elder abuse victims more likely to have injuries to the left cheek or zygoma (22% versus 3%) or on the neck (15% versus 0%) or ear (6% versus 0%).

CONCLUSION

Specific, clinically identifiable differences may exist between unintentional injuries and those from physical elder abuse. This includes specific injury patterns that infrequently occur unintentionally.

Developing the Emergency Department Elder Mistreatment Assessment Tool for Social Workers Using a Modified Delphi Technique

Elder mistreatment is common and has serious consequences. The emergency department (ED) may provide a unique opportunity to detect this mistreatment, with social workers often asked to take the lead in assessment and intervention. Despite this, social workers may feel ill-equipped to conduct assessments for potential mistreatment, due in part to a lack of education and training. As a result, the authors created the Emergency Department Elder Mistreatment Assessment Tool for Social Workers (ED-EMATS) using a multiphase, modified Delphi technique with a national group of experts. This tool consists of both an initial and comprehensive component, with 11 and 17 items, respectively. To our knowledge, this represents the first elder abuse assessment tool for social workers designed specifically for use in the ED. The hope is that the ED-EMATS will increase the confidence of ED social workers in assessing for elder mistreatment and help ensure standardization between professionals.

Effects of the COVID-19 Outbreak on Elder Mistreatment and Response in New York City: Initial Lessons

New York City is currently experiencing an outbreak of COVID-19, a highly contagious and potentially deadly virus, which is particularly dangerous for older adults. This pandemic has led to public health policies including social distancing and stay-at-home orders. We explore here the impact of this unique crisis on victims of elder mistreatment and people at risk of victimization. The COVID-19 outbreak has also had a profound impact on the organizations from many sectors that typically respond to protect and serve victims of elder mistreatment. We examine this impact and describe creative solutions developed by these organizations and initial lessons learned in New York City to help inform other communities facing this pandemic and provide guidance for future crises.

Developing a rigorous, systematic methodology to identify and categorize elder mistreatment in criminal justice data

Elder mistreatment is complex, with cases typically requiring integrated responses from social services, medicine, civil law, and criminal justice. Only limited research exists describing elder mistreatment prosecution and its impact. Researchers have not yet examined administrative prosecutorial data to explore mistreatment response, and no standardized analytic approach exists. We developed a rigorous, systematic methodologic approach to identify elder mistreatment cases in prosecutorial data from cases of crimes against victims aged ≥60. To do so, we operationalized elements of the accepted definition of elder mistreatment, including expectation of trust and vulnerability. We also designed an approach to categorize elder mistreatment cases, using the types of charges filed, into: financial exploitation, physical abuse, sexual abuse, verbal/emotional/psychological abuse, and neglect. This standardized methodological approach to identify and categorize elder mistreatment cases in prosecution data is an important preliminary step in analyzing this potentially untapped source of useful information about mistreatment response.

Can artificial intelligence help identify elder abuse and neglect?

A health care encounter is a potentially critical opportunity to detect elder abuse and initiate intervention. Unfortunately, health care providers currently very seldom identify elder abuse. Through development of advanced data analytics techniques such as machine learning, artificial intelligence has the potential to dramatically improve elder abuse identification in health care settings.

EXISTING STRATEGIES FOR ELECTRONIC DATA COLLECTION BY ELDER ABUSE MULTI-DISCIPLINARY TEAMS

Elder abuse cases often require integrated responses from social services, medicine, civil legal, and criminal justice. Multi-disciplinary teams (MDTs), which meet periodically to discuss and coordinate interventions for complex cases, have developed in many communities. Little is known about how these MDTs collect case-level data. Our objective was to describe existing strategies of case-level electronic data collection conducted by MDTs across the United States as a preliminary step in developing a comprehensive database strategy. To identify MDTs currently collecting data electronically, we used a snowball sampling approach discussing with national leaders. We also sent an e-mail to the National Center for Elder Abuse listserv inviting participation. We identified and reviewed 11 databases from MDTs. Strategies for and comprehensiveness of data collection varied widely. Databases used ranged from a simple spreadsheet to a customized Microsoft Access database to large databases designed and managed by a third-party vendor. Total data fields collected ranged from 12-338. Types of data included intake/baseline case/client information, case tracking/follow-up, and case closure/outcomes. Information tracked by many MDTs, such as type of mistreatment, was not captured in a single standard fashion. Documentation about data entry processes varied from absent to detailed. We concluded that MDTs currently use widely varied strategies to track data electronically and are not capturing data in a standardized fashion. Many MDTs collect only minimal data. Based on this, we have developed recommendations for a minimum data set and optimal data structure. If widely adopted, this would potentially improve ability to conduct large-scale comparative research.

TRENDS IN GERIATRIC PHYSICAL ASSAULT INJURIES TREATED IN U.S. EMERGENCY DEPARTMENTS, 2006-2015

Trends in Geriatric Physical Assault Injuries Treated in US Emergency Departments, 2006-2015 Older adults are common victims of assault, many of which may result in severe injuries. Our objective was to understand temporal and demographic trends in geriatric assault injuries treated at U.S. Emergency Departments (EDs) and to compare these trends to assault injuries in younger adults. We conducted an analysis of assault injuries in patients aged ≥60 compared to patients aged 18-59 treated in EDs during 2006-2015 using the National Electronic Injury Surveillance System-All Injury Program Special Study of Assaults, which collects data from a nationally representative stratified probability sample of U.S. hospitals. Total geriatric assaults seen in EDs increased from 35,135 in 2006 to 69,657 in 2015, a 98% increase. These injuries increased as a percentage of all geriatric injuries treated from 0.9% to 1.1%. Assaults in older men increased 119%, while assaults in older women increased 68%. Among age groups, the biggest percentage increases were among adults aged 60-64 (138%) and aged 65-74 (89%). ED visits for injuries associated with physical elder abuse increased from 13,241 in 2006 to 27,406 in 2015, a 107% increase. During this period, number of younger adults treated for assault did not significantly change. We concluded that geriatric assault injuries, particularly in older men in younger age groups, are dramatically increasing. Further research is needed to better understand these assaults to develop prevention strategies.

Review of Programs to Combat Elder Mistreatment: Focus on Hospitals and Level of Resources Needed

BACKGROUND

Elder mistreatment is common and has serious social and medical consequences for victims. Though programs to combat this mistreatment have been developed and implemented for more than three decades, previous systematic literature reviews have found few successful ones.

OBJECTIVE

To conduct a more comprehensive examination of programs to improve elder mistreatment identification, intervention, or prevention, including those that had not undergone evaluation.

DESIGN

Systematic review.

SETTING

Ovid MEDLINE, Ovid EMBASE, Cochrane Library, PsycINFO Elton B. Stephens Co. (EBSCO), AgeLine, CINAHL.

MEASUREMENTS

We abstracted key information about each program and categorized programs into 14 types and 9 subtypes. For programs that reported an impact evaluation, we systematically assessed the study quality. We also systematically examined the potential for programs to be successfully implemented in environments with limited resources available.

RESULTS

We found 116 articles describing 115 elder mistreatment programs. Of these articles, 43% focused on improving prevention, 50% focused on identification, and 95% focused on intervention, with 66% having multiple foci. The most common types of program were: educational (53%), multidisciplinary team (MDT) (21%), psychoeducation/therapy/counseling (15%), and legal services/support (8%). Of the programs, 13% integrated an acute-care hospital, 43% had high potential to work in low-resource environments, and 57% reported an attempt to evaluate program impact, but only 2% used a high-quality study design.

CONCLUSION

Many programs to combat elder mistreatment have been developed and implemented, with the majority focusing on education and MDT development. Though more than half reported evaluation of program impact, few used high-quality study design. Many have the potential to work in low-resource environments. Acute-care hospitals were infrequently integrated into programs.

Disclosure among victims of elder abuse in healthcare settings: a missing piece in the overall effort toward detection

Elder abuse remains a largely hidden problem in our society and only a small minority of victims are connected to formal support/protective services. Healthcare settings have been identified as a critical milieu to uncover cases of elder abuse; however, under-detection in these settings is a major issue. Victimization disclosure is an important component within the overall detection effort, yet it has received little attention in the elder abuse literature. Drawing on relevant literature from other domains of family/interpersonal violence, this article highlights the disclosure process, as well as disclosure barriers, facilitators, and competencies to consider when working with older adults.

Emergency department provider perspectives on elder abuse and development of a novel ED-based multidisciplinary intervention team

BACKGROUND

An ED visit provides a unique opportunity to identify elder abuse, which is common and has serious medical consequences. Despite this, emergency providers rarely recognise or report it. We have begun the design of an ED-based multidisciplinary consultation service to improve identification and provide comprehensive medical and forensic assessment and treatment for potential victims.

METHODS

We qualitatively explored provider perspectives to inform intervention development. We conducted 15 semistructured focus groups with 101 providers, including emergency physicians, social workers, nurses, technologists, security, radiologists and psychiatrists at a large, urban academic medical centre. Focus groups were transcribed, and data were analysed to identify themes.

RESULTS

Providers reported not routinely assessing for elder mistreatment and believed that they commonly missed it. They reported 10 reasons for this, including lack of knowledge or training, no time to conduct an evaluation, concern that identifying elder abuse would lead to additional work, and absence of a standardised response. Providers believed an ED-based consultation service would be frequently used and would increase identification, improve care and help ensure safety. They made 21 recommendations for a multidisciplinary team, including the importance of 24/7 availability, the value of a positive attitude in a consulting service and the importance of feedback to referring ED providers. Participants also highlighted that geriatric nurse practitioners may have ideal clinical and personal care training to contribute to the team.

CONCLUSIONS

An ED-based multidisciplinary consultation service has potential to impact care for elder abuse victims. Insights from providers will inform intervention development.

Identifying and Initiating Intervention for Elder Abuse and Neglect in the Emergency Department

Elder abuse and neglect are common and may have serious medical and social consequences but are infrequently identified. An emergency department (ED) visit represents a unique but usually missed opportunity to identify potential abuse and initiate intervention. ED assessment should include observation of patient-caregiver interaction, comprehensive medical history, and head-to-toe physical examination. Formal screening protocols may also be useful. ED providers concerned about elder abuse or neglect should document their findings in detail. ED interventions for suspected or confirmed elder abuse or neglect include treatment of acute medical, traumatic, and psychological issues; ensuring patient safety; and reporting to the authorities.

Relation between severity of liver disease and renal oxygen consumption in patients with cirrhosis

BACKGROUND

Worsening cirrhosis may lead to increased renal O2 metabolism caused by activation of neurohumoral antinatriuretic substances.

AIMS

To evaluate the relation between the severity of liver disease, sodium excretion, and neurohumoral antinatriuretic substances on the one hand and renal O2 metabolism on the other in patients with cirrhosis.

METHODS

Renal O2 consumption and haemodynamics as well as plasma concentrations of noradrenaline, renin, and aldosterone were measured. Investigations were performed in 14 patients with Pugh's grade A, 43 with grade B, and 29 with grade C liver disease.

RESULTS

Renal O2 consumption significantly increased with the severity of cirrhosis (grade A, 8.9 (1.6); grade B, 15.5 (1.3); grade C, 18.0 (1.5) ml/min/m2). Plasma concentrations of noradrenaline, renin, and aldosterone significantly increased while mean arterial presssure and systemic vascular resistance significantly decreased with the severity of the disease. A significant inverse correlation was found between renal O2 consumption and sodium excretion. A significant direct correlation was found between plasma levels of noradrenaline and aldosterone on the one hand and renal O2 consumption on the other. Renal blood flow and the glomerular filtration rate did not differ significantly between patients with grade C and grade A or B disease.

CONCLUSIONS

This study shows for the first time that, in patients with cirrhosis, worsening of the disease is associated with an increase in renal O2 consumption. The results suggest that increased renal O2 consumption is due to renal tubular sodium retention caused by increased levels of neurohumoral antinatriuretic substances. This neurohumoral activation is related to cirrhosis induced vasodilation.

Elevated circulating cardiac troponin I in patients with cirrhosis

It has been shown that certain patients with cirrhosis have asymptomatic cardiac abnormalities that have not yet been explained. Thus, cardiac troponin I, a specific marker of myocardial injury, has been measured in patients with cirrhosis without previous cardiac disease. Thirty-two consecutive patients (age 49 +/- 11) with cirrhosis and normal ECG were selected, 22 of which were alcoholic. Hemodynamic investigations were performed. Left ventricular function and mass were evaluated by echocardiography. Serum creatine kinase MB mass, myoglobin, and cardiac troponin I concentrations were measured. Cardiac troponin I concentrations were elevated in 10 patients (32%) (range 0.06-0.25 microg/L) whereas creatine kinase MB mass and myoglobin were normal in all patients. Abnormal troponin I values were not related to the severity of cirrhosis, to the degree of portal hypertension, or to other hemodynamic values. In contrast, elevated serum cardiac troponin I concentrations were related to a decreased stroke-volume index (P <. 05) and a decreased left ventricular mass (P <.05). These results show a high prevalence of slightly elevated serum cardiac troponin I in patients with cirrhosis, especially in those with alcoholic cirrhosis. Elevated troponin I is associated with subclinical left ventricular myocardial damage. These findings may be linked to a lack of left ventricular adaptation in certain patients with cirrhosis and alcoholic cardiomyopathy.

Influence of transjugular intrahepatic portosystemic shunts (TIPS) on tissue oxygenation in patients with cirrhosis

AIMS/BACKGROUNDS: The aim of this prospective study was to evaluate the influence of transjugular portosystemic intrahepatic shunts (TIPS) on tissue oxygenation in patients with cirrhosis and refractory ascites.

METHODS

Five shunted patients were included in the study. The blood and tissue oxygenation values were analyzed 12 days and 4 months after TIPS procedure. The results were compared with those observed in patients treated by paracentesis.

RESULTS

Unlike patients treated by paracentesis, PaO2 values remained unchanged throughout follow-up in shunted patients. After the TIPS procedure, there was a transient increase in systemic O2 transport and O2 uptake and a transient decrease in O2 saturation of hepatic oxyhemoglobin. After 4 months, TIPS resulted in an increase in PCO2 values and bicarbonate concentrations.

CONCLUSIONS

The TIPS procedure seems to prevent the decrease in PaO2 observed in patients treated by paracentesis and may improve the respiratory alkalosis of cirrhosis.

Studies of portal hemodynamics and hepatic oxygen consumption during acute liver allograft rejection

Hemodynamics and oxygen variables, plasma cytokines, and histological features of a liver tissue sample obtained by transvenous biopsy were evaluated during 65 episodes of acute rejection. The hepatic venous pressure gradient was significantly higher in patients with acute rejection than in those without (5.1+/-0.3 vs. 3.1+/-0.2 mmHg, P<0.01). The increase in pressure gradient was related to the severity of rejection lesions. Hepatic blood flow was significantly lower in patients with than in those without acute graft rejection (1.28+/-0.11 vs. 1.75+/-0.13 L/min, P<0.05). Plasma interleukin-6 levels were significantly increased in patients with acute rejection and positively correlated with pressure gradient values. In patients with acute rejection, a significant decrease in hepatic venous oxygen content (-16%) was associated with a significant increase in hepatic oxygen consumption (+24%), whereas hepatic oxygen transport did not change significantly. In treated patients with a favorable response, the pressure gradient decreased significantly by 46%, but it remained elevated in patients who later developed chronic graft rejection. In conclusion, this study confirms that acute graft rejection may induce an increase in portal pressure, which is related to the severity of rejection lesions. It also shows that acute rejection decreases hepatic blood flow and increases hepatic oxygen consumption. In addition, it suggests that the hepatic venous pressure gradient might be useful to determine the outcome of rejection.

[Influence of anemia on hemodynamic changes in patients with cirrhosis]

OBJECTIVE

The aim of this retrospective study was to evaluate the systemic and splanchnic hemodynamic changes induced by anemia in patients with cirrhosis.

METHOD

148 patients (Child-Pugh A: 46 patients, Child-Pugh B: 64 patients and Child-Pugh C: 38 patients) were included in the study. Anemia was defined by a blood hemoglobin level < 12 g/dL. A systemic and splanchnic hemodynamic study was performed in all patients.

RESULTS

A significant elevation of the hepatic venous pressure gradient was observed in Child-Pugh A patients with anemia but not in Child-Pugh B and C patients. In the 2 latter groups, cardiac index was significantly increased and systemic vascular resistance decreased in patients with anemia.

CONCLUSION

Anemia may worsen the hemodynamic changes associated with cirrhosis.

Systemic and splanchnic hemodynamic changes in patients with hepatic schistosomiasis

Although hepatic schistosomiasis is a common cause of portal hypertension, only a few hemodynamic studies, in humans, have been published on this subject. The aim of this study was to determine the systemic and splanchnic hemodynamic changes in hepatic schistosomiasis and to evaluate the influence of liver fibrosis on these changes. A retrospective analysis of a series of 13 patients with hepatic schistosomiasis who had undergone hemodynamic studies was performed. Portal or perisinusoidal fibrosis was present at liver biopsy in 8 patients. The control group included 22 patients with chronic hepatitis and normal hepatic venous pressure gradients. Patients with schistosomiasis exhibited high cardiac index (4.11 +/- 1.15 l.min-1.m-2 vs 2.99 +/- 0.85 l.min-1.m-2; p < 0.05) and low systemic vascular resistance (1039 +/- 316 dyn.s.cm-5 vs 1334 +/- 336 dyn.s.cm-5; p < 0.05). The hepatic venous pressure gradient and hepatic blood flow were normal. Azygos blood flow was markedly increased (0.90 +/- 0.66 l.min-1 vs 0.13 +/- 0.04 l.min-1; p < 0.05). Hemodynamic values were not significantly different between patients with liver fibrosis and those without fibrosis at liver biopsy. In conclusion, patients with hepatic schistosomiasis had a hyperkinetic systemic and splanchnic circulation. In patients with esophageal varices, a normal hepatic venous pressure gradient confirmed presinusoidal portal hypertension. The presence of portal or perisinuoidal fibrosis did not influence hyperdynamic splanchnic state.

Interpleural analgesia with bupivacaine following thoracotomy: ineffective results of a controlled study and pharmacokinetics

STUDY OBJECTIVE

To evaluate intrapleural analgesia with bupivacaine following partial pulmonary resection and to determine pharmacokinetic parameters of bupivacaine with epinephrine.

DESIGN

Prospective, randomized study.

SETTING

Thoracic surgical clinic of a university-affiliated general hospital.

PATIENTS

Eighteen consecutive patients (13 men, 5 women) scheduled for pulmonary surgery by posterolateral thoracotomy.

INTERVENTIONS

Bupivacaine was administered through an intrapleural catheter as a bolus dose of either 40 ml of 0.25% bupivacaine with epinephrine (0.5 mg per 100 ml of solution) (n = 10) or 20 ml of 0.5% bupivacaine with epinephrine (0.5 mg per 100 ml of solution) (n = 8) up to three times daily for a maximum time of 4 days.

MEASUREMENTS AND MAIN RESULTS

Subjective evaluation of pain was performed using the visual analog scale (VAS) before and after each injection by response to spontaneous pain, coughing, deep breathing, and incision palpation. Maximum peak concentration (C Max) and maximum time to reach the peak concentration (T Max) were assessed after the first and last injections. Although VAS pain score decreased significantly, pain relief was not sufficient. C Max and T Max after the first and last injections were not significantly different between the two groups. In each group, C Max after the last injection was significantly higher than after the first injection.

CONCLUSIONS

Intrapleural analgesia conducted with 40 ml of 0.25% bupivacaine with epinephrine or 20 ml of 0.5% bupivacaine with epinephrine was insufficient for pain, despite high plasma bupivacaine concentration.

[Hypoglycemia]

After vagal collapsus, hypoglycemia is the emergency most often seen in the dental office. It usually happens among the treated diabetic population; there are approximately one million diabetics in France. Its sudden appearance requires an emergency treatment with oral or IV intake of glucose, or the injection of glucagon. Hypoglycemia is defined by a drop of the blood glucose level below the normal values. Of sudden onset, the clinical signs of hypoglycemia can vary, specially the neurological and psychiatric manifestations, and they can lead to a coma. The objective diagnosis relies on the blood glucose level.

Diffuse large cell (histiocytic) lymphoma of the spleen. Clinical and pathologic characteristics of ten cases

Ten patients with diffuse large cell (histiocytic) lymphoma of the spleen had a characteristic clinical presentation and pathologic findings. Patients presented with left upper quadrant pain, fever, weight loss, and an elevated sedimentation rate. Imaging studies revealed an enlarged spleen with a discrete mass in all cases. Moderate to massive splenomegaly (average weight, 1025 g) was found at laparotomy; a single large mass or multiple confluent nodules with extensive central necrosis replaced 85% to 90% of the parenchyma. The tumor transgressed the splenic capsule in nine of ten cases, and either invaded or was adherent to the diaphragm, stomach, pancreas, or abdominal wall. Lymph nodes in the splenic hilum or retroperitoneum were frequently involved. Seven patients were in Ann Arbor Stage II, and three were in Stage I. Eight of the ten lymphomas were subclassified as centroblastic (large noncleaved cell) and two were immunoblastic. The B-cell lineage of six tumors was established by the presence of monoclonal immunoglobulin. Despite combination chemotherapy, with or without radiation, three of the seven patients whose follow-up was adequate died in less than 2 years; four are alive at 7, 12, 12, and 81 months, respectively, the last two with recurrent lymphoma. Large cell lymphoma of the spleen is a likely diagnosis in patients who present with left upper quadrant pain, fever, and radiographic evidence of a splenic mass.
